' PART II PROPOSED OPERA'1'IOI4S <br />E, Final Reclamation - <br />1. Physical Construction: 'Throughout the 10 years of operations in this <br />site, reclamation is to proceed with tl+e mining. Overburden stripping <br />and placement shall b2 doae so that the final configurations of mounds, <br />islands and lake banks will result. 'Che principle shall be first to create <br />the site of topsoil fill by mining the underlying grave]., then to fill with <br />strippings. This is illustrates] for each year's operations in drawings 3-1 <br />- through 3-11. Planting will he done on the final land corms as the last <br />phase of operations each spring {a) <br />Z. Aims and goals of reclamation: The primary theme of the reclaniaticn <br />- plan is to create an area of more biological diversity than is now present cn this <br />site~b)It is well known that the most st:-able ecosysterns are those \aith the <br />(c} <br />greatest diversity, tiVa propose to recreate portions o; the native vegetation <br />(d) <br />- and habitat. By defining the structure of natural analogs (e.n., riparian <br />woodlands, cattail marshes, wet sedge meadows, etc,) along Boulder Creel: <br />and in the front range of Colorado, we should be able to return various parts <br />_ (e) <br />of this site to condi.tious that lflcely existed a hundred years ago. A <br />principal element in the reclamation will be the riparian woodlands area just <br />I <br />south of Boulder Creek (see figure 6) . The cottonwoods and willows are <br />~ native to the flood plant and will provide both a screen during excavation and <br />J <br />_ habitat for wildlife. The large lake on the eastern ettd of the site will he <br />J designed with a minimum of spawning areas to promote a warm water fishcty. <br />-{ The islands will be of low profile with cattails and willows. The fslands will <br />J ~ serve as goose and duc}: nesting habitat. Several smaller, shallower oxbow <br />(Footnotes on page 16a,) _ 16 - <br />
